NID’s annual flushing program begins to clean treated water lines
(Nov. 2, 2022) NID will begin its annual flushing program to clean the District’s treated water distribution system on Nov. 28, 2022.
During the process, the District’s crew will tap fire hydrants, allowing water to flow through main lines at a higher velocity to wash away any residue that may have collected through the year. Water will be dechlorinated and flushed from the hydrants up to 400 gallons a minute.
The work will continue through March of 2023, starting in Cascade Shores and ending in North Auburn.
NID’s flushing program is conducted annually to ensure water pipelines function properly to deliver high-quality drinking water.
Flushing does not usually affect water service in the area. Customers may experience momentary pressure changes when nearby hydrants are tapped. Customers also may experience some turbid or discolored water, which can be cleared quickly by opening a faucet and letting the water run.
If you have any questions about the flushing program, please call the NID operations desk at (530) 271-6885.
